hey bot, can i ask a question?
Of course! Go ahead and ask your question.
The formula vw=f ⋅ λ describes the relationship between the speed of a wave (vw), and its frequency (f) and wavelength (λ).
For example, if a wave has a frequency of 120 Hz and a wavelength of 5m, it would have a speed of 600 m/s.
In one or two sentences, describe what would happen to the frequency of this wave if the wavelength is increased to 10m but the speed stays the same at 600 m/s.
(2 points)
If the wavelength is increased to 10m but the speed stays the same at 600 m/s, the frequency of the wave would be reduced to 60 Hz (halved).
Red tape can be used to repair a broken taillight on a car. In one or two sentences, explain how different colors of light are transmitted, reflected, and absorbed by this kind of tape.(2 points)
Red tape transmits and reflects red light wavelengths, while absorbing other colors and preventing them from passing through, which is why it can be used to repair a broken taillight on a car.
You want to make a photo album for your friend. In three to five sentences, describe at least one advantage and one disadvantage of choosing a digital photo album rather than a physical one. Analyze a potential solution to the disadvantage.(4 points)
One advantage of choosing a digital photo album is that it allows for easy sharing and access, as it can be shared via email or social media platforms. One disadvantage is that it lacks the tangible and sentimental value of a physical album. A potential solution to this disadvantage could be to include printed photographs within the digital album, such as making a photo book through a service like Shutterfly or Walgreens, so that the recipient can still have a physical representation of the memories.
"There is danger that because of a great victory women will believe their whole struggle for independence ended. They have still far to go. It is for the Woman's Party to decide whether there is any way in which it can serve in the struggle which lies ahead to remove the remaining forms of woman's subordination."
—Alice Paul, The Suffragist, 1921
